Cousteau/SEA enviro sealing issue

[buddhasummer]

From aqualung tests on regulators with dry seal :
At ambient pressure,IP= 9 bar ( 135 PSI)
At 20 meters IP = 9,8 bar (+0.8 b)
At 50 meters. IP= 11 bar (+2 b)
So, when you pressurized your 1stage at ambient pressure, you should not see any change in your IP pressure, if you have 40 or 50 psi ( +3 bar) , the problem is somewhere else than the dry seal transmitter

Yes, I have the manual and agree with you.

The best thing to do with aqualung first stages is box them up and send them to a glutton for punishment type.

They are not mine but a friends otherwise I'd send them your way.

Oh no please don’t.

Update.

Tried new diaphragm only jumped about 10psi as opposed to 50. Filed down transmitter in small increments and retried, after three attempts, fitted end cap no movement in psi, it's stable.

It would appear the issue was two part, old aged diaphragm and the transmitter being ever so slightly too long.

Thanks for all the suggestions and advice.

This case is closed, successful conclusion. Cheers.

regulator without pressure, shaking it,can you hear the transmitter moving inside ?( sound )

With original diaphragm no rattle at all, now it rattles a tad. Good tip, cheers.

I'll check it at the end of a dive, ip should have changed at low pressure, if not, I'll look at it again, hoping I didn't take too much off the transmitter. I think I'm good though.

I did note that the spring pad "looked" taller than those I've seen before, from memory anyway.

It was taken out yesterday for a dive, performed as it should, no change in ip until around 40 bar as expected. Thanks once again.
